Conteúdo: | Evaluation of eleven R. japonicum strains by N2(C2H2)-fixation on soybean showed a significant correlation with nodule mass, nodule numbers, plant dry weight, plant height, seed size, and seed yield. Strains ranking high in N2(C2H2)-fixation rate generally ranked high in nodule mass and plant dry weight. However, slightly better correlations were obtained between N2(C2H2)-fixation rate and seed yield than between nodule mass and seed yield. This observation was attributed to strain that either exhibited plant chlorotic effects, were inefficient in N2-fixation, or were classified as parasitic. These strains often produce substantial nodule mass, but were inefficient in N2(C2H2)-fixation rate. For these reasons, the acetylene technique is considered advantageous over using nodule mass in strain evaluation.
